Abstract: The flotation reagents from acidic olive oil are made by transesterification of acidic olive oil. Acidic olive oil is olive oil having an acid value high enough to render it unsuitable for consumption, typically greater than 3.3% and/or between 3.3-7%. Transesterification of the olive oil with methanol converts fatty acids in the olive oil to an ester fraction and a glycerol fraction. The ester fraction may be sulfonated and used as the collector in a reverse flotation process, selectively removing the carbonate gangue from phosphate-carbonate rock in the froth, leaving phosphates in the sink. The glycerol fraction may be used without modification as the collector in the reverse flotation process. Both fractions are highly selective for carbonates, substantially reducing loss of phosphates in the froth.

Abstract: The system and method for connecting a square concrete-filled steel tubular column to a reinforced concrete footing includes a short steel pipe partially embedded in the footing, the pipe having a top end having flanges extending radially therefrom, the top end extending into a cavity in the footing having an elliptical top opening and circular base, the flanges extending above the base. An elliptical base plate is welded to the bottom of the tubular steel column, the base plate having a circular opening defined therein and a plurality of spaced flange slots depending therefrom. The bottom end of the column is lowered into the cavity, the elliptical base plate passing through the elliptical opening in the cavity, and the column is rotated 90° to interlock the flanges with the flange slots. The cavity is filled with concrete grout, and the square or rectangular steel column is filled with concrete.

Abstract: The Moringa oleifera nanoparticles may be synthesized by harvesting Moringa leaves, drying the Moringa leaves, powdering the dried Moringa leaves, suspending the powdered Moringa leaves in a solution, and spraying the solution into boiling water under ultrasonic conditions to obtain Moringa nanoparticles. The Moringa nanoparticles may be encapsulated by dissolving the Moringa nanoparticles and gum olibanum in ethanol to produce a mixture, injecting the inert organic phase of the mixture into an aqueous solution containing PVA, and homogenizing the aqueous solution. The Moringa nanoparticles may be useful in preventing the growth of cancer cells and in treating diabetes by inhibiting ?-glucosidase and/or ?-amylase activity.

The background tab extends parallel to and beneath the tab of a dental shade guide retained in the slot at the dental shade guide attachment end of the handle.

Abstract: The extraction of benzene from benzene/cyclohexane mixture described herein is a process that removes benzene from a benzene/cyclohexane mixture with high selectivity, resulting in an enriched cyclohexane content in the retentate. The process involves adding an aqueous solution of poloxamer 188 to the benzene/cyclohexane mixture and waiting for the mixture to partition into an organic layer above an aqueous layer. Benzene, being more polar than cyclohexane, is selectively drawn into the aqueous layer. Benzene is then removed from the aqueous layer by pervaporation through a composite PDMS (polydimethylsiloxane)/polystyrene membrane. Cyclohexane is recovered from the retentate by drawing off the organic layer of the retentate by any known method. About 97% of benzene has been removed from a 50-50 wt % mixture by pervaporation in the static mode, and about 99% by pervaporation in the continuous mode.

Abstract: The present disclosure provides HRG-Mn3O4 hybrid nanoparticles. The HRG-Mn3O4 hybrid nanoparticles do not pose any cytotoxicity at normal physiological conditions and therefore they are nontoxic and biocompatible at physiological conditions. The HRG-Mn3O4 hybrid nanoparticles under exposure of laser light cause massive cellular damage indicating their potential use for photodynamic therapy of cancer. The HRG-Mn3O4 hybrid nanoparticles enhance the magnetic resonance signals from cancer cells and exhibit excellent MRI contrast property for tumor imaging and are therefore useful contrast agent.

Abstract: The fixed space regainer is a resin band designed to regain space in the gap between the remaining teeth when a tooth is lost. The band has opposing concave ends that provide bonding surfaces or anchors that attach to the remaining teeth on opposite sides proximal to the gap and an elongate connecting band between the bonding surfaces. The regainer is made from a biocompatible elastic material so that the connecting band will arch when installed across the gap and exert resilient pressure against the remaining teeth proximal to the gap to regain the space lost by narrowing that occurs by loss of the tooth, thereby providing proper spacing for growth of a permanent tooth or installation of a cosmetic replacement. The regainer may be designed by the dentist in software from a digital impression and made by 3D printing or additive manufacturing.
